' 2 Claims. (01. 210-515) This invention relates to liquid separators or extractors and more particularly to a device for extracting cream or the like from a bottle.

An object of this invention is to provide an extractor or separator which can be projected into the neck of a milk bottleso as to remove or skim the cream from the milk, the cream having first risen to the top of the bottle.

Another object of this invention is to provide an extractor or separator of this kind which is so constructed that it can be kept in a sanitary condition at all times and which can be readily and cheaply manufactured.

A further object of this invention is to provide in a device of this kind means whereby the liquid extracted from a bottle or the like will not drain out of the device during the removal of the device from the container.

A still further object of this invention is to rovide in a device of this kind a valve which is of flexible construction and can be readily removed from the body of the device so as to permit cleaning thereof, the valve also having means whereby upon suction of the liquid into the device, theliquid is drawn in from the side of the valve rather than from the center thereof.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:-

Figure 1 is a longitudinal section partly in detail taken substantially through the center of a device constructed according to the preferred embodiment of this invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is an enlarged fragmentary sectional view taken on the line 3-3 of Figure 1.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a cylinder which is provided at one end with a bead or rib 13 and the numeral 11 designates a bulb of resilient or elastic construction engaging about the cylinder 10.

This bulb 11 is provided with a constricted end portion 12 engaging the bead or enlargement 13 so that the open end of the bulb will be removably held against movement relative to the cylinder 10. The opposite end of the cylinder 19 is constricted or provided with a tapering portion 14, thereby providing a nozzle through which the liquid drawn into the cylinder 10 by the bulb 11 will pass and through which the liquid .will be discharged upon compression of the bulb 11 after the cylinder 10 has been filled.

By constricting or tapering the end of the cylinder 10, as at 14, a valve seat is provided which is engaged by a valve member 15. This valve member 15 has an outer surface conforming to the seat 14 and is provided with a stem 16 extending beyond the discharge end 14. A plate or disk 1'? is secured to the outer end of the stem 16 and is of a diameter substantially equal to or slightly larger than the diameter of the valve. 15. 1

4 A plurality of ribs having vertically disposed portions 18 and horizontal' portio-ns 19 aredisposed between the valve 15 and the plate 17. The vertical portions 18 of the ribs which are generally designated as 20, provide means whereby the valve 15 is held concentrically of the discharge orifice of the cylinder 10 while permitting movement of the valve 15 into either open or closed position. The laterally projecting portions 19 of the ribs 20 are adapted to engage against the outer end of the cylinder 1i) where it is' constricted, as at 14, so as to prevent the drawing into the cylinder of the valve 15 including the plate 17.

When the ribs 19 engage the end of the cylinder 10, the liquid is drawn into the cylinder between pairs of ribs from the side of the cylinder so that where the cylinder 10 is inserted into the neck of a milk bottle for extracting or removing the cream, the cream will not be drawn into the cylinder 10 from a point concentric from the cylinder but. from points disposed laterally of the cylinder.

The tapered or constricted end portion 14 also provides means whereby the insertion of the cylinder 10 into the milk bottle or other receptacle is facilitated, and as the cylinder 10 is substantially equal to the diameter of the bottle opening, the bulb 11 is released'at least partially simultaneously with the insertion so that the cream will not overflow, and when the bulb 11 is completely released so as to form a partial vacuum within the cylinder 10, the cream will be drawn into the cylinder 10 from a lateral direction rather than from a point forwardly or below the orifice engaged by the valve 15.

The bulb or suction member 11 may be '0: any desired size but is preferably of a size sufficient so that when this bulb is compressed and subsequently released when it assumes its natural 110 shape, the cylinder 10 will be substantially filled with the desired liquid.

The cylinder 10 may be constructed of any desired material but in the present instance, it is constructed of glass so that it can be readily and easily cleansed. and is of a diameter such that a bottle cleaning brush can be projected thereinto for cleaning.

The periphery of the cylinder 10 is provided with a plurality of graduations 21 which are disposed in longitudinally spaced position along the surface of the cylinder and certain of these graduations 21 are defined by indicia or markings in the form of numerals 22. These grad-' uations 21 and indicia 22 may be raised from the surface of the cylinder 10 or, if desired, may be pressed into the cylinder as may be desired.

In the use and operation of this device, the bulb or suction member 11 be initially compressed, and in order to eifectively compress the member ll, the valve member 15 is moved inwardly of the cylinder 10 and unseated from the valve seat 14 by pressin the plate 17 onto a plane surface or engaging it with a finger or other article so that the air within the bulb l1 and the cylinder 10 may be substantially expelled therefrom. With the bulb l1 compressed, the cylinder 10 may then be projected into the neck of a bottle or container and the bulb 11 permitted to expand simultaneous with the insertion of the bulb, thereby drawing the liquid or cream through the nozzle 14 and the suction will also move the valve 15 into open position. The liquid will pass between pairs of ribs 20 and due to the plate 17, the liquid cannot be drawn into the cylinder 10 from a point concentric therewith but must be drawn from a point lateral to the longitudinal axis of the cylinder 10.

The cream or liquid in the cylinder 10 may be removed by first en aging the plate 17 with the interior of a receptacle so as to move the valve 15 into open position. The bulb 11 can then be collapsed or compressed, thereby discharging the liquid from the cylinder 10. In order to clean the cylinder 10, the plate 1'7 may be turned sideways a slight degree and due to the fact that the valve 15 is preferably made of flexible or tion Without departing from the'spirit thereof,

such changes and modifications being restricta only by the scope of the following claims.

What is claimed is:

1. An extracting means comprising a substantially cylindrical tube, a suction bulb on one end of the tube, a tapering valve seat formed with the other end of the tube, a valve for said seat and disposed inwardly of the tube, a stem formed with the valve, ribs carried by the stem and holding the valve concentrically of the valve seat, a plate formed with the stem, and ribs engaging the stem and the plate to limit the movement of the valve inwardly of the tube, said plate preventing suction of liquids from a point alining with the longitudinal axis of the cylinder while permitting suction of liquids from a point laterally of the longitudinal axis of the cylinder.

2. An extracting means comprising a cylindrical tube, a suction means on one end of the tube, a valve seat on the other end oi the tube, an automatically closing valve engaging said seat, holding means carried by said valve and engaging the lower end of the tube for holding the valve concentrically of the seat, and laterally extending means formed with said holding means to limit the movement of the valve inwardiy of the tube while permitting liquids to pass about the valve from a point laterally of the tube, said limiting means including a plate carried by said valve forwardly of the end of the tube and alining with the longitudinal axis thereof and preventing flow of the liquids into the other end of the tube from a point alining with the longitudinal axis of the tube.
